Zinc oxide nanoparticles (ZnO NPs) exhibit distinctive characteristics, making them highly sought-after in many sectors. Nevertheless, conventional techniques for producing ZnO-NPs are linked to environmental and health hazards due toxic substances. In this review, we study zinc synthesized from plant extracts their subsequent biomedical uses detail. Research shows that several different employed manufacturing ZnO nanoparticles. Leaves, fruits, seeds, roots, complete plants all included these extracts. Phytochemicals such as phenolic compounds, alkaloids, flavonoids, terpenoids a part of biological matrices. compounds show bioreduction mechanism, act stabilizing reducing agent. The attributes (NPs), including size, shape, crystallinity, may be altered by adjusting the extract variety, concentration, synthesis conditions. Consequently, formed display notable diversity physical chemical subsequently impacting functionality. manufactured using green methods extensive, beneficial effects antibacterial activity against various pathogens, anti-inflammatory possible anticancer activities. Nanoparticles have been integrated into wound dressings, used carriers medication delivery, utilized biosensing imaging applications. enhanced biocompatibility reduced toxicity green-processed techniques, comparison those made approaches, make very appealing use contexts. Moreover, paper examines mechanisms, explicitly focusing on involvement phytochemicals processes reduction stabilization. Additionally, emphasizes difficulties potential future directions optimizing processes, increasing capacity, facilitating therapeutic
